The *Chopin - Godowsky Revolutionary Etude N<sup>o</sup> 12* is arranged for the **left hand only**, and we're only informed about this by a note under the title. Please see the excerpt below:

[![Chopin - Godowsky Revolutionary Etude][1]][1]

I am currently writing a piece for piano only for the left hand. I have only one staff with the treble clef for piano. Without any additional notes, we would play it with the right hand autonomously.

I would like to know if I, too, should just indicate to play the piece with the left hand only as in the excerpt above&mdash;or are there any other (notation) signs to show this?

Thank you.
